03 Altima will turn but won't start

I'm having the same problem! and I just found a video on YouTube that might help… I think my problem is the fuse! So I opened up my fuse box to the left of my steering wheel, and I took out the very last fuse on the right, which is labeled 10,and I see that it is broken, busted ,whatever !! so first thing in the morning I'll be going to buy another fuse and hopefully this is what the problem has been and is ! :-)

The starter …..start with checking all your fuses

In my experience it seems that either The Crank shaft positioning sender is faulty or the cam shaft positioning sensor is faulty or maybe even both I recommend you to go to the nearest Auto part store and buy a scan tool and run a diagnostics test to find out for sure which one it is if not something else related to the two and remember to always remove the negative battery cable before changing any electrical parts to avoid possible surging and further damaged to your vehicle hope this helps God bless

I was driving this 2.5 altama stop by my mom's took shower sit down eat and went to leave and it would turn over but no start this my only transportation appreciate any

My 06 Altima actually stalled out on me while I was doing 50mph. It lost all engine power, but my radio & headlights were still on. I coasted to the nearest side road & put in park, turned the ignition off & waited a few minutes, then tried to restart it. Nothing. No crank, no clicking, no start. But my battery ( hence my alternator) was working just fine. So I had it towed to my home & began troubleshooting. After verifying that the battery, starter, alternator, fuel system, fuses & all wiring were all in good working order, I also made sure that the Cam, Crank & O2 sensors were good. After checking all of this, I still had no clue why my car suddenly died in transit & wouldn't restart. At my wits end, I made a last ditch effort at DIY diagnostics & began searching terms & keywords on Google. After reading 999 pages that were not helpful, I finally found a page that explained something that I hadn't even considered, much less tried. The ignition relay (switch) inside the fuse box under the hood. Upon determining that it was indeed ‘bad', I hurried to the nearest auto parts place, bought a new one, and immediately replaced it. And VOILA….my car started on the first try!! !
